  2. 2. ABSTRACTBiometrics is an automated method of capturing a person’s uniquebiological data that distinguishes him or her from another individual. Irisrecognition has emerged as one of the most powerful and accurateidentification techniques in the modern world. It has proven to be most foolproof technique for the identification of individuals with out the use ofcards, PIN’s and passwords. It facilitates automatic identification where byelectronic transactions or access to places, information or accounts are madeeasier, quicker and more secure.

  4. 4. INTRODUCTIONIn today’s information age it is not difficult to collect data about an individual and usethat information to exercise control over the individual. Individuals generally do not wantothers to have personal information about them unless they decide to reveal it. With therapid development of technology, it is more difficult to maintain the levels of privacycitizens knew in the past. In this context, data security has become an inevitable feature.Conventional methods of identification based on possession of ID cards orexclusive knowledge like social security number or a password are not altogetherreliable. ID cards can be almost lost, forged or misplaced: passwords can be forgotten.Biometric technology has now become a viable alternative to traditional identificationsystems because of its tremendous accuracy and speed. This paper explores the conceptof Iris recognition which is one of the most popular biometric techniques. Thistechnology finds applications in diverse fields.
  5. 5. IRIS RECOGNITIONIris identification technology is a tremendously accurate biometric. Iris recognitionleverages the unique features of the human iris to provide an unmatched identificationtechnology. So accurate are the algorithms used in iris recognition that the entire planetcould be enrolled in an iris database with only a small chance of false acceptance or falserejection. The technology addresses the FTE (Failure To Enroll) problems which lessenthe effectiveness of other biometrics. Only the iris recognition technology can be usedeffectively and efficiently in large scale identification implementations. The tremendousaccuracy of iris recognition allows it, in many ways, to stand apart from other biometrictechnologies.

  7. 7. ANATOMY, PHYSIOLOGY AND DEVELOPMENTOF THE IRISThe iris is a protective internal organ of the eye. It is a thin diaphragm stretching across theanterior portion of the eye and supported by lens. At its base the eye is attached to the eye’sciliary body. At the opposite end it opens into a pupil. The cornea and the aqueoushumor in front of the iris protect it from scratches and dirt, the iris is installed in its owncasing. It is a multi layered structure. It has a pigmented layer, which forms a coloring thatsurrounds the pupil of the eye. One feature of this pupil is that it dilates or contracts inaccordance with variation in light intensity.
  8. 8. The properties of the iris that enhance its suitability for use in highconfidence identification system are those following:-1. Extremely data rich physical structure about 400 identifying features2. Genetic independence no two eyes are the same.3. Stability over time.4. Its inherent isolation and protection from the external environment.5. The impossibility of surgically modifying it without unacceptable risk to vision.6. Its physiological response to light, which provides one of several natural tests againstartifice.7. The ease of registering its image at some distance forms a subject without physicalcontact. unobtrusively and perhaps inconspicuously8. It intrinsic polar geometry which imparts a natural co-ordinate system and an origin ofco-ordinatesIRIS AS A POWERFUL IDENTIFIER
  9. 9. SCIENCE BEHIND THE TECHNOLOGYThe design and implementation of a system for automated iris recognition canbe subdivided in to 3.1. Image acquisition2. Iris localization and3. Pattern matching
  10. 10. APPLICATIONS◊ Computer login: The iris as a living password.◊ National Border Controls: The iris as a living password.◊ Telephone call charging without cash, cards or PIN numbers.◊ Ticket less air travel.◊ Premises access control (home, office, laboratory etc.).◊ Driving licenses and other personal certificates.◊ Entitlements and benefits authentication.◊ Forensics, birth certificates, tracking missing or wanted person◊ Credit-card authentication.◊ Automobile ignition and unlocking; anti-theft devices.◊ Anti-terrorism (e.g.:— suspect Screening at airports)◊ Secure financial transaction (e-commerce, banking).◊ Internet security, control of access to privileged information.◊ “Biometric—key Cryptography “for encrypting/decrypting messages.
  11. 11. DISADVANTAGES OF USING IRIS FORIDENTIFICATION Small target (1 cm) to acquire from a distance (1m) Located behind a curved, wet, reflecting surface Obscured by eyelashes, lenses, reflections Partially occluded by eyelids, often drooping Deforms non-elastically as pupil changes size Illumination should not be visible or bright Some negative connotationsEven though conventional methods of identification are indeedinadequate, the biometric technology is not as pervasive and wide spread asmany of us expect it to be. One of the primary reasons is performance. Issuesaffecting performance include accuracy, cost, integrity etc.
  12. 12. The figure illustrates a comparison between coast and accuracy. The cost representedhere is a typical incremental investment needed for accruing a commercially availablebiometric sensor and for implementing and identity authentication system.The biometric system has the disadvantages of being intrusive bothphysically and socially. They require the users to position their bodies relativeto the sensor and then pause for a second.
  13. 13. IRIS RECOGNITION: ISSUESThe technology requires a certain amount of user interaction the enroller must holdstill in a certain spot, even if only momentarily. It would be very difficult to enroll oridentify a non-cooperative subject. The eye has to have a certain degree of lighting toallow the camera to capture the iris; any unusual lighting situation may affect theability of the camera to acquire its subject. Lastly, as with any biometric, a backupplan must be in place if the unit becomes inoperable. Network crashes, powerfailure, hardware and software problems are but a few of the possible ways in which abiometric system would become unusable. Since iris technology is designed to be anidentification technology, the fallback procedures may not be as fully developed as ina recognition schematic. Though these issues do not reduce the exceptionaleffectiveness of iris recognition technology, they must be kept in mind, should acompany decide to implement on iris-based solution.
  14. 14. CONCLUSIONThe technical performance capability of the iris recognition process far surpasses thatof any biometric technology now available. Iridian process is defined for rapidexhaustive search for very large databases: distinctive capability required forauthentication today. The extremely low probabilities of getting a false match enablethe iris recognition algorithms to search through extremely large databases, even of anational or planetary scale. As iris technology grows less expensive, it could very likelyunseat a large portion of the biometric industry, e-commerce included; its technologicalsuperiority has already allowed it to make significant inroads into identification andsecurity venues which had been dominated by other biometrics. Iris-based biometrictechnology has always been an exceptionally accurate one, and it may soon grow muchmore prominent.
